ADJUSTABLE REVOLVlNG HOLDER FOR GAME-BOARDS, &c.

SEEGIFIOATION forming part of Letters Patent No. 674,782, dated May 21, 1901.

Application filed April 10, 1900. Serial No. 12,357. (No model.)

T0 all 1077/0712 it may concern:

Be it known that LITERMAN HENRY LIEBEN- BERG, a citizen of the United States, residing at Platteville, in the county of Grant and State of W'isconsin, have invented a new and useful Adjustable Revolving Holder,of which the following is a specification.

My invention relates to improvements in adjustable revolving holders for game-boards, and pertains to a device which is particularly adapted for holding and revolving gameboards, such as crokinole or bombards, also painting and drafting boards, or objects of a like nature.

In the accompanying drawings, Figure 1 is a central vertical sectional view of my invention. Fig. 2 is a top plan view. Fig. 3 is a bottom plan view. Fig. 4 is a detailed sectional view of one of the revolving arms. Fig. 5 is a detailed sectional view of one of the stationary arms,sho wing the adjustable cleat. Fig. 6 is a transverse sectional view of the arm B.

Referring now to the drawings, A indicates the top of an ordinary table; B,two stationary arms resting thereon. The stationary arms 1;- intersect at right angles and are mortised, so to bring their lower and upper surfaces in the same plane. Braces n, extending between the arms B, serve to hold the arms in a rigid position. The lower surface of the arms B and braces 11 may be covered with felt or like material to prevent scratching or scarring the table. The revolving portion D may be made of a single plate, with longitudinal grooves for the reception of adjustable cleats, as will be explained hereinafter; butI prefer to carry out my invention in the following manner:

D indicates the revolving arms, which are arranged at right angles and mortised at the point of intersection, thus bringing the upper and lower surfaces of each arm in the same plane. At the point of intersection of the respective arms B and D, I provide a vertical circular recess adapted to receive a pivotal pin H, about which the arms D revolve. On the end of the arms D, I provide cleats X, the said cleats havinga longitudinal recess g and are laterally adjustable by means of a setsorew f, thus enabling the operator to adjust the arms to receive and revolve various-sized boards. The cleats X are provided with notches or rabbets for receiving the depending flange M of a crokinole or other board K.

The rabbet R will also serve this purpose.

Thecleats X having a shoulder adapted to receive the depending flange of a game-board and being laterally adjustable, it will be seen that the game-board can be readily fastened or locked and prevented from slipping while it is revolved.

At each end of the stationary arms B, I provide a depending laterally-adjustable cleat or bearing-block O for the purpose of adjusting the holder to various-sized tables. The adjustment of the block Ois accomplished by providing a recess or groove 6 in the end of arms B for receiving the screw 01, which is operated by the thumb-screw c, as illustrated in Fig. 5.

From the above description it will be seen that I provide a light yet durable revolving holder for game-boards or similar objects, which can be readily adjusted and securely attached to various-sized tables in a manner which will prevent the movement of the arms B, thus preventing them from scratching or scarring the table.

Through the medium of the cleats X on the revolving arms D it will be seen that the gameboards or like objects of different sizes can be securely held in position without necessarily resting the center of the board on the arms D, thus protecting the lower surface of the board.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is V 1. In a revolving game-board holder comprising the lower stationary portion B provided with laterally adjustable bearingblocks 0, pivotal pi'n H, upper revolving portion D, means for adjusting the upper portion to receive game-boards of diiferent sizes, substantially as described.

2. In a revolving game-board holder, the laterally-extending arms B provided with depending bearing-blocks O, braces 71, the revolving portion D having laterally-adjustscrewfscrewedinto the end of the arms D and adapted to control the lateral adjustment of the cleats X, substantially as described.

In testimony whereof I have signed my 15 name to this specification in the presence of two subscribing witnesses.

HERMAN HENRY LIEBENBERG.
